MOUNTING FOR PARTS ON MOTOR VEHICLES.

Application med January 4, 1926, serial No.

This invention relates to the mountings of engines or gear boxes, preferably rfor use 4011 motor vehicles, and it relates to that type of mounting wherein -thereis interposed between an attachment device such as an arm, bracket, or -the like, on the engine or, gear boX and a supporting member such as the chassis frame, apad of rubber.

' The object of the present invention is to provide a durable mounting of this kind which will be very efficient in insulating.,r the .engine or gear box from the frame and in reducing noise vand vibration.

Accordingr to this invention, the pad or block of rubber is gripped vbetween and fits closely withinoppo-sitely arranged recesses carried by the attachment device and the supporting member respectively.

' In the accompanying drawings,

Figure 1 is a section through part of a upporting arm, showing one method of carrying this upon an element of a motor vehicle frame, and

Figure 2 is a similar View showing a modification.

Like numerals indicate like parts throughout the drawings.

In the arrangement shown inFigure 1, the. engine or gear box is provided with an attachment device such as an arm or bracket- 2 which is adapted to be mounted upon a supporting member 3 o n the vehicle frame, the arm usually resting upon this member and being bolted to it, either directly, or, lin some eases, with an intermediate strip of rubber, or other resilient packing between 1 pering as shown.

the arm and the frame member.

In applying the'present invention, the arm is formed n its upper face with a recess 4 and below with a recess 5, these recesses ta- The arm is bored at 6 to receive the bolt 7 whereby it is-secured to the frame, and upon this bolt, above and below th-e arm, are rubber blocks 8 and 9 which are coned to correspond to the shape of the recesses and are backed up by recessed washers 10 upon the bolt;

,79,184, and in Great Britain March .11, 1925.

-An importantfeature of the invention is that the rubber blocks 8 and 9 are slightly larger in diameter than the recesses 4 and 5, so that they have to be forced by means of the bolt into the recesses. The result is thatV the rubber is compressed in every direction, which is aided by the fact that' the washers 10 are recessed through being flanged at 11.

In the4 modification shown in Figure 2,-the

rubber .blocks 12 are spherical, the recesses 13 in the arm and the washers 14 are of corresponding shape. In this arrangement also the rubber blocks are slightlv larger than the recesses so that they will unot bottom fully in the recesses until 4the nut on the bolt 7 has been considerably tightened, so that the rubber blocks are then under compression in all directions.

By this means very long life is impartedv t-o the rubber blocks and an efficient insulation of the engine or gear box from the on said rubber block, a recess forsaid block' in sai-d arm, an upper recess on the upper face ofv said arm, an upper rubber. block in said recess, a recessed upper washer resting on said upper rubber block and a bolt drawing said upper washer down towards said frame.

2. The device of claim 1, said rubber blocks being under compression in said re cesses in all directions.

In testimony whereofI have signed my.

name to this specification.
